No joy with 9x transmitter and SmartieParts SP Basic firmware programmer for Er9x install

er9x is the best known firmware. It has a superb range of features and is well supported by the community. Well worth trying out.

They all measure correct. I'm putting the SP board back in now.

OK, as jhsa said, try reading the processor with the THR and AIL switches forwards.

There's a change but not in a very good way perhaps. I put the board back in, made sure the pins that I could see (all but RST and GND) were well aligned on their pads, and powered up. Transmitter booted normally. Tried my usual Read Firmware test, unit beeped (I got the usual target not responding error from avrdude) and instead of restarting normally now shows EEPROM Error on all attempts to boot. If I try another Read Firmware the transmitter beeps as it apparently resets, then goes right back to EEPROM error and beeps continuously. Looks like I wiped it, even though the target not responding errors continue. I'm tempted to try a write but will wait for advice. Thanks.

If it wasn't for the target not responding errors (or maybe due to them) this thread may be relevant:

If the "go ahead and try flash" route is recommended (despite the target errors), I'd appreciate being pointed at the latest stable version of er9x (or opentx -- still not clear on the best choice between these) that would be safe to try flash at this point. Thanks.

I think I would still try the read at this point.. Did you try with the THR and AIL switches ON as well?

Whatever you do, DO NOT use the -F option as AvrDude might suggest.. That option can brick your radio..

No difference with the switches. The tx is just beeping continuously from power on with EEPROM error. When I try to read with the SP board there is a very short break in the beeping and then back to EEPROM error. As I mentioned in the OP, I did originally try a -F on a read, but there was no sign of any negative effect (the results I got when I did that are in the OP). The normal firmware was always booting properly until this afternoon. Thanks.

Tried holding EXIT while powering on (based on a RESET thread I found). The unit powers up with continuous beeping, says RESTORE for maybe 20 seconds or so (beeping continuous), then back to EEPROM ERROR.

This has been one of the most problematic cases I've come across. And as he says in the first post... I'm stumped. We assumed it was a faulty programmer so I sent a replacement, but no change in behavior. I suppose it is *possible* to get two bad programmers in a row... but then that strange device ID when he tried -F got me wondering if the problem is with the 9X's fuses. Other than risking another -F and using something like AVR burner to read the fuses... I'm not really sure how to confirm.

Your continuing assistance has been appreciated. Unfortunately, I've long been notorious for finding the problematic cases in all sorts of technology contexts! I'm tempted to go ahead and try a write if I have a recommended image in hand. Somehow that read attempt this afternoon changed the status from the stock firmware to EEPROM ERROR -- even though it was a read. There don't seem to be many routes to getting past EEPROM ERROR without flashing something else ... or not?

Bit of a long shot, but you could try reading with -v -v on the command line. This turns on "verbose output" that might give a hint of what problems are occuring. Post the resulting output.

Here it is. This is all while the EEPROM ERROR continuous beeping was in progress (again, these were very briefly interrupted when I gave the read command):

Re: No joy with 9x transmitter and SmartieParts SP Basic firmware programmer for Er9x install

Post by PNaz » Sun Jan 03, 2016 2:57 am

I have done some more troubleshooting of one of my M128a boards. I removed the SP Basic board, connected the transmitter back up, turned on the power and got "eprom error" and loud tone from the speaker. I then turned on the power while holding exit button and got the "restore" message. It looks like I have the original firmware with a bad eeprom. I then hardwired an aspusb programmer to the mother board. I am now able to read firmware and fuses from the motherboard as well as writing the fuses. Reading the eprom gives a corrupted eprom message as expected. When I try to write firmware arvdude goes through the complete write sequence until the verification and then fails. I have included the firmware read file before trying to write a new firmware, after the failed write, and the screen shots in two parts of the avrdude output from the bad write.

Is it possible that Flysky is using M128a chips that are failing the quality control test but are able to take a 64Kb firmware? That might explain why they are using the M128 chips which should be more expensive than the M64.

Some significant progress. I found eepe was useless because it wanted to read before write to do backups. So I switched to using avrdude directly to try a write:

avrdude -c usbasp -p m64 -B 1000 -U flash:w:er9x.hex

Still no response from target, until I put a bit of manual pressure on the SP board during the attempt:

avrdude: set SCK frequency to 1000 Hz
avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.10s

avrdude: Device signature = 0x0e0000
avrdude: Expected signature for ATmega64 is 1E 96 02
Double check chip, or use -F to override this check.

avrdude done. Thank you.

Then back to EEPROM error and solid beeping. So far I'm not finding obvious references to what this signature error means, but at least there's communications going on of some sort. Any ideas? Thanks!

More progress. Apparently successful read -- though some file-related errors. This was still while putting pressure on the SP board manually -- otherwise no target response. Transmitter is still in EEPROM ERROR mode and beeping continuously (except during that read operation). Signature error I got on write does not seem to be happening on read (I pulled out the -B 1000 since it appeared unnecessary and was slowing things way down).


avrdude -c usbasp -p m64 -U flash:r:backup.hex


avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.00s

avrdude: Device signature = 0x1e9602

avrdude: writing output file "backup.hex"
avrdude: error opening backup.hex: No such file or directory

avrdude: safemode: Fuses OK (H:FF, E:89, L:0E)

avrdude done. Thank you.

No luck with writes yet, though. Still in EEPROM ERROR mode with solid beeping.

Re: No joy with 9x transmitter and SmartieParts SP Basic firmware programmer for Er9x install

Post by TT0002 » Sun Jan 03, 2016 6:41 am

SUCCESS! It appears that I now have er9x installed (should be r819, not certain that's completely current though). Various "throttle not idle" warnings and such but I haven't done any setup yet.

I initially got it writing on Linux via eepe/avrdude but received a first byte mismatch error on verify and then the unit appeared bricked. However, I found considerable discussion suggesting that this problem in particular is a Linux-related issue with avrdude, so I tried again on Windows and it wrote, verified and booted.

All of this had to be done while I was exerting considerable finger pressure on the SP board in a particular zone throughout all reading/writing/verify ops.

Otherwise, right back to the "target doesn't respond" errors. So for one reason or another, a pin or pins (other than reset and ground, which clearly already worked -- even though the ground pin seemed to have the weakest spring) are not making adequate contact in the normal install without that added pressure.

Since I am not dealing with many models and my need to read/write eeprom data from the unit will be extremely limited, and given that I hopefully won't need to upgrade the firmware frequently after this, I am not overly concerned about this situation even if it means the SP card won't work without the unit being open and pressure applied -- and I may simply remove the usb connector from the SP cable and stow the cable inside.

I am frankly reluctant to physically move or change anything related to the SP board at this point. I could try tighten the screw with the washer, but that risks the board working loose, or causing the board to rotate despite efforts to hold it steady. So long as the board isn't too likely to come loose at the washer from any rough handling/vibration of the transmitter (the washer contact area with the board is quite limited) I think the status quo might be OK (I may put some electrical tape or something on there as backup protection against the board coming loose on the washer screw side).

I'll add that at least to my eyes the SP board seems to have a very, very slight outward bow when installed. I don't know if that's from the screw positions of the SP board, the washer screw situation, or some oddity with this particular batch of 9x units, but it might well explain the need to apply manual pressure for successful operations.

For now, all's well that ends well. If anyone needs more details on the procedures that eventually worked, please let me know.

Thanks again everyone for their advice on this, and special thanks to Steven at SmartieParts for his continuing assistance in getting this going, and his great customer support in general as well!

Best,

L

Post by s_mack » Sun Jan 03, 2016 7:38 am

Very odd. Since we knew the GND and RST pins were making contact, and they are on the "outsides", that means either the SP board is bowed up in the middle or your 9X is dipping down... either case seeming bizarre as to why. Or perhaps one of the springs in the pins failed. But... with 2 boards in a row? Then again, maybe it wasn't really two in a row. Your first, if I recall correctly, you eventually broke a pin off moving the board around trying to get the alignment right. So maybe you had the same symptom (target not found) but two completely different problems.

In any case, I recognize that the screw hold gaff on my board certainly doesn't help with troubleshooting a situation like this. I do want to note that most people have had no problems at all (out of hundreds sold - all with the screw hole problem since we're on the initial batch - perhaps a dozen have had troubles). Still, I do apologize for the troubles.

Let's face it, these 9x tx units are not exactly mil spec, and their build quality is ... well ... minimalist let's say. So the fact that you got your boards working at all in this environment is a testament to your skill. And again, all's well that ends well. Thanks.

Did you try cleaning the pads with some alcohol? Sometimes they have some oxid that prevents electrical contact with the pins.

For those cases there's a glass fibre eraser pen in my toolbox since long time ago.
It's suitable for many things like cleaning contact paths of the servo's linear pots
of Horizon's UM and UMX planes
or removing solder masks ...

Success for me as well. After reading about TT0002's problem with linux I tried using Win10 to flash the transmitter. I had been using my macbook and achieved partial success like he did with linux. With the Win10 computer I had absolutely no problems. The flash went well with no verification errors. Disconnected the transmitter and turned it on again. The eePe eeprom error came up this time, so I pressed a button and the eprom was formatted. The transmitter now works correctly. I connected it to the Win10 computer again, read the eeprom, added a model file from another er9x transmitter, and wrote the eeprom to the new transmitter. All went well. This was all with a hard wired usbasp.

Steve, the other transmitter I tried to use the SP Basic on has not been flashed with the hardwired usbasp. Would you like to have a look at it with the SP Basic installed? I tried to flash it again with the Win10 computer and still no luck with it. I did try putting some pressure on the SP Basic while reading. I am down the valley from you, south of Penticton, so no problem getting it to you.

Yeah, for the record, I tried cleaning the pads in multiple ways. But without that additional manual pressure, I apparently just couldn't get contact. Now that er9x is on there which was the key goal, I may take another look at that situation before I close the unit up again.

The issue that avrdude apparently routinely fails on verification of er9x on Linux (and Mac too?) -- but succeeds on Windows -- is troubling. That's one of those "should not happen" situations given the structure of the software, and appears to be confirmed from numerous sources. It's especially a problem for folks who don't run Windows, of course. This really needs to be understood and appropriately FAQ'd for now, to help prevent a lot of wasted time going forward.
